Cataldo then opened a small schoolhouse at Saint Michael's Mission where both Native American and white students attended. In order to expand the mission, he was able to purchase two parcels of land totalling 320 acres (1.3 km2) for $936. The first parcel of 280 acres (1.1 km2) north of Spokane was to be used for the relocation of St. Michael's mission. This location became the site for the Jesuit scholasticate Mount Saint Michael. The second parcel of 40 acres (160,000 m2) was located on the Spokane Falls, near modern downtown Spokane on the Spokane River. In 1881 Cataldo was encouraged to use the second parcel of land for the establishment of a college to serve the growing Catholic population in the area. It was here that Cataldo established Gonzaga College, now Gonzaga University. Cataldo died in Pendleton, Oregon on April 9, 1928, at the age of 92.
